The strength of ODS superalloys has not been so satisfactory as to attract much attention for application in turbine blades. As one of the advanced materials programs supported by MITI, cooperative works were undertaken to develop ODS superalloys superior to monocrystalline alloys. Mechanical properties of new ODS alloys developed in Japan were summarized to evaluate their potentials for turbine blade applications. The project tasks included isothermal forging and diffusion bonding studies for blade fabrication.

In this study, the welded joints of dissimilar titanium alloys Ti600/Ti-22Al-25Nb were strengthened by isothermal forging. Different deformation parameters, including temperature, deformation speed, and reduction, were chosen. By isothermal forging, the original coarse dendritic grains of the welded joints were broken up effectively to form a large number of equiaxed grains. Meanwhile, many second phases were precipitated in the grain. Additionally, the dynamic globularization kinetics of second phases within the welded joints were quantitatively characterized and investigated. The results showed that the dynamic globularization kinetics and globularization rate were sensitive to the deformation conditions, and were promoted by a reduced strain rate and an elevated deformation temperature.
